BACKGROUND

The background description provided herein is for the purpose ofgenerally presenting the context of the disclosure. Work of thepresently named inventors, to the extent it is described in thisbackground section, as well as aspects of the description that may nototherwise qualify as prior art at the time of filing, are neitherexpressly nor impliedly admitted as prior art against the presentdisclosure.

A battery connector has an overall structure which occupies a smallspace and provides stable current, and is often installed in anelectronic apparatus such as a computer or a server to provide anadditional power source or a supplemental power source. Generally, abattery connector includes an insulating body having a batteryaccommodated therein, a limiting portion located at a top portion of theinsulating body and being block-shaped to stop the battery fromdetaching from the insulating body, and a positive pole terminal and anegative pole terminal retained in the insulating body and abutting thebattery. In an assembling process of the conventional modern batteryconnector, the positive pole terminal and the negative pole terminal aregenerally pre-installed in the insulating body. Then, a device, such asa robotic arm, is used to grab the battery and to place it downward onthe stopping portion, and another device is used to press the batterydownward, such that the battery passes the limiting portion and abutsthe positive pole terminal and the negative pole terminal, therebycompleting the assembly of the battery connector. However, the batteryhas a relatively small structure, and in the process of the robotic armrapidly placing the battery onto the insulating body, it is difficultfor the whole battery to just align with and abut the top of thelimiting portion. Generally, the battery partially abuts the limitingportion and partially protrudes out of the insulating body. Thus, thebattery may easily impact with the stopping surface of the limitingportion and falls out of the insulating body when being placed therein.Alternatively, in the subsequent process of pressing the battery, theforce applied to the battery at its two sides may be unbalanced due tothe battery partially protruding out of the insulating body, whichcauses the battery to fall out of the insulating body or not to beinstalled in the accurate location, thereby increasing the defect rateof the products, and increasing the human and production costs.

Therefore, a heretofore unaddressed need to design a new batteryconnector exists in the art to address the aforementioned deficienciesand inadequacies.

In this embodiment, the abutting portion 312 abuts thebattery 1 by providing a protrusion. The extending portion 311 extendsupward from the abutting portion 312. The pressing portion 32 extendsupward from a top end of the extending portion 311. Further, aprotruding portion 313 is formed by punching the extending portion 311.The protruding portion 313 and an abutting surface of the abuttingportion 312 are located at a same side. Two opposite side edges of theprotruding portion 313 are connected with the extending portion 311, anda bottom end of the protruding portion 313 is a hollow structure. Thebottom end of the protruding portion 313 is broken from the extendingportion 311, such that the extending portion 311 forms a breaking hole314, and the bottom end of the protruding portion 313 limits the battery1 from moving upward. Further, an inclined angle of the top surface ofthe protruding portion 313 is equal to an inclined angle of the secondoblique surface 241, such that the two ends of the battery 1 may beplaced on the limiting portions 23 and the protruding portion 313 in arelatively balanced way. The pressing portion 32 has an oblique section321 inclined toward a direction away from the second accommodating space6, and an upright section 322 extending upward from the oblique section321. The two sides of the upright section 322 respectively abut theouter sides of two stopping walls 24 to prevent the first section 31from being excessively inclined. In this embodiment, the oblique section321 is partially located in the second accommodating space 6. In otherembodiments, the oblique section 321 may be completely located in thesecond accommodating space 6. The second section 34 is accommodated inthe first fixing slot 25 to fix the positive pole terminal 3 to theinsulating body 2. In addition, an extending height of the secondsection 34 does not pass beyond a height of a connecting location of thefirst section 31 and the pressing portion 32, such that the pressingportion 32 has sufficient space to move in a front-rear directionwithout being abutted. The first soldering leg 33 passes through thebottom wall 21 to be soldered and fixed to an electronic component (notshown in the drawings).

As shown in FIG. 1, FIG. 2 and FIG. 8, the negative pole terminal 4includes a mounting portion 41 extending upward and retained in thesecond fixing slot 28.

The second soldering leg 43 includes a lateralsection 431 extending toward the first accommodating space 5 from thesurface of the mounting portion 41 and in contact with the bottom wall21, and a vertical section 432 bending and extending downward from atail end of the lateral section 431 and passing through the bottom wall21 (that is, the second soldering leg 43 is formed as an inversed Lshape). The vertical section 432 is soldered and fixed to an electroniccomponent, and the surfaces of the lateral section 431 and the verticalsection 432 have protrusions. In addition, the two limiting portions 23are respectively located below the two stopping walls 24 at the twoopposite sides of the negative pole terminal 4, and the two limitingportions 23 are equally distanced from the positive pole terminal 3, Thetwo limiting portions 23 and the protruding portion 313 are providedopposite to each other to stop the top end of the battery 1 altogether,thus limiting the battery 1 from moving upward. Further, the twolimiting portions 23 and the protruding portion 313 are located on asame horizontal plane, such that the battery 1 may enter the firstaccommodating space 5 downward more stably.

For convenience of understanding, the mounting of the battery 1 into theinsulating body 2 according to certain embodiments of the presentinvention will be described hereinafter.

The battery 1, when being mounted downward into the insulating body 2,has an initial position and a final position. When the battery 1 isguided downward by the second oblique surface 241 and mounted into thesecond accommodating space 6, as shown in FIG. 4, FIG. 5 and FIG. 6, thebattery 1 is located at the initial position, and the battery 1 abutsand is located above the limiting portions 23 and the protruding portion313 and is in contact with the guide surface 242. Then, the battery 1 ispressed downward such that the battery 1 is guided by the first obliquesurface 231 to pass the limiting portions 23 and the protruding portion313 and enter the first accommodating space 5, as shown in FIG. 7. Inthis case, the battery 1 is located at the final position, and thebattery 1 is located below the limiting portions 23 and the protrudingportion 313 to respectively abut the positive pole terminal 3 and thenegative pole terminal 4.

To sum up, the battery connector 100 according to certain embodiments ofthe present invention has the following beneficial effects:

1. The second accommodating space 6 is provided above the firstaccommodating space 5 and the limiting portions 23 in the insulatingbody 2, and the second accommodating space 6 is in communication withthe first accommodating space 5. In assembly, the battery 1 is firstlyguided downward into the second accommodating space 6. Then, the battery1 is pressed downward to pass the limiting portions 23 and enter thefirst accommodating space 5, thus abutting the positive pole terminal 3and the negative pole terminal 4. Thus, in the process of placing thebattery 1, even if the battery 1 is not mounted into and aligned withthe insulating body 2, the battery 1 will be firstly guided into thesecond accommodating space 6 in the downward mounting process andlocated above the limiting portions 23, such that the battery 1 ismounted into the insulating body 2 without being ejected out, thusensuring the battery 1 is guided by the inner wall surface of the secondaccommodating space 6 in the subsequent pressing process to smoothlypass the limiting portions 23 and enter the first accommodating space 5to stably abut the positive pole terminal 3 and the negative poleterminal 4 in the first accommodating space 5, and enhancing theassembly yield rate of the battery connector 100.

2. In assembly, when the battery 1 is in contact with the top portion ofeach of the stopping walls 24, the second oblique surface 241 may guidethe battery 1 to enter the second accommodating space 6 downward. Theguide surface 242 may guide the battery 1 to be placed horizontally evenif the battery 1 enters the second accommodating space 6 obliquely,allowing the battery 1 to be subsequently pressed to enter the firstaccommodating space 5. The first oblique surface 231 guides the battery1 to pass the limiting portions 23 to enter the first accommodatingspace 5. The guide surface 242, the second oblique surface 241 and thefirst oblique surface 231 further facilitate assembly of the battery 1into the insulating body 2.

3. The first notch 26 provides a reserved function, allowing thenegative pole terminal 4 to be retained in the second fixing slot 28.The depth of the first notch 26 recessing downward is less than a depthof the second notch 27 recessing downward, such that the stopping walls24 and the side wall 22 has a larger deformation space. When the battery1 is placed slightly obliquely in the second accommodating space 6, andthe battery 1 is pressed downward, the stopping walls 24 and the sidewall 22 may expand outward properly, thus ensuring the battery 1 to bepressed to enter the first accommodating space 5 without breaking thestopping walls 24 and the side wall 22.

4. The two limiting portions 23 are respectively located at the twoopposite sides of the negative pole terminal 4 and provided opposite tothe protruding portion 313, and the two limiting portions 23 and theprotruding portion 313 are located on the same horizontal plane. The twolimiting portions 23 and the protruding portion 313 form a triangularshape, and altogether stop three locations of the top end of the battery1, thereby ensuring the battery 1 not to fall from the firstaccommodating space 5. Further, the two limiting portions 23 and theprotruding portion 313 are located on the same horizontal plane, suchthat the battery 1 may stably enter the first accommodating space 5downward, either horizontally or obliquely.

5. The protruding portion 313 is formed by firstly forming a breakinghole 314 on the extending portion 311, and then punching above thebreaking hole 314 to form the protruding portion 313 with elasticity.The two opposite side edges of the protruding portion 313 are connectedwith the extending portion 311 and the bottom end of the protrudingportion 313 is a hollow structure. The structural design of theprotruding portion 313 allows the protruding portion 313 to return toits original shape rapidly when the battery 1 passes the protrudingportion 313 downward and the protruding portion 313 is pressed laterallyby the battery 1 and deforms. Further, the bottom end of the protrudingportion 313 may match with the limiting portions 23 to stop the top endof the battery 1 altogether.

6. The positive pole terminal 3 includes a pressing portion 32 extendingupward and a first section 31 bending downward from the pressing portion32. The oblique section 321 is partially located in the secondaccommodating space 6. The oblique section 321 and the guide surface 242altogether guide the battery 1 to be placed in the second accommodatingspace 6, and a first section 31 and a second section 34 opposite to eachother and forming a U-shaped structure. Since the second section 34 isfixed to the first fixing slot 25, the first section 31 may move in thefront-rear direction relative to the second section 34. The firstsection 31 allows the pressing portion 32 to have certain returningelastic force, such that the positive pole terminal 3 does not easilyshake when the battery 1 is ejected out. In addition, the extendingheight of the second section 34 does not pass beyond the height of theconnecting location of the first section 31 and the pressing portion 32,such that the pressing portion 32 has sufficient space to move in thefront-rear direction without being abutted.

7. The second soldering leg 43 is located between the two contact arms42, and has the lateral section 431 and the vertical section 432,allowing the negative pole terminal 4 to be stably inserted in andconnected to the insulating body 2. When the battery 1 and the contactarms 42 abut each other, the lateral section 431 abuts the bottom wall21 to stabilize the negative pole terminal 4, such that the negativepole terminal 4 does not easily shake and become loose to detach fromthe second fixing slot 28.

8. In addition, the thickness of the battery 1 is less than or equal tothe extending height of the stopping walls 24 (that is, the distancebetween the top surface of each of the limiting portions 23 and the topend of the insulating body 2), ensuring the depth of the secondaccommodating space 6 to be sufficiently deep, such that the battery 1does not fall out of the insulating body 2 when the battery 1 iscompletely mounted into the second accommodating space 6, therebyfacilitating automatic assembly of the battery 1, and further enhancingthe assembly yield rate of the battery connector 100.
